Rose plant named ‘BENsiete’

ABSTRACT

This new rose plant, ‘BENsiete’, bears fully double flowers with hybrid tea form, primarily one to a stem. Flowers can last well on the plant, opening and fading slowly, and ten days or more as cut flowers. Fragrance is moderate. The plant is of a medium size and upright growing habit. ‘BENsiete’ is well suited as a garden perennial, a large container plant and for cut flowers.

Genus and species: Rosa hybrida.

Varietal denomination: ‘BENsiete’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of hardy,bush-type rose plant. This new variety is from a single seedlingoriginated by Frank A. Benardella under controlled conditions in agreenhouse in Millstone Township (formerly, Englishtown), N.J., bycrossing the following two rose plants:

-   -   The seed parent is a pink miniature rose from this same breeding        program, ‘Perfection’ (not patented).    -   The pollen parent is a red hybrid tea, ‘JACecond’, (U.S. Plant        Pat. No. 11,369).        This resulting new rose has been given the code name of        ‘BENsiete’ and the trade name of Ambiance.

The primary goal of this breeding program is to produce unique roseswith award winning, hybrid tea form on plants having favorableattributes that will increase public appeal. To achieve this goal rosesare selected for this hybridizing program primarily for their awardwinning, hybrid tea form. Pertaining to this particular cross, bothparents have been noted for their exhibition form flowers that are oftenborne one to a stem. Both are traits visible in this new invention.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of hardy,bush-type rose plant. The most significant feature is the lightapricot-pink color of its fully double, hybrid tea form flowers thatexpand, on average, to 2¾ to 3½ inches. It has several other attributesthat further set it apart from all other presently available roses, ofwhich I am aware. They are its unique combination of:

-   -   Flowers that open slowly and last a long time on the plant;    -   Flowers that are borne primarily singly;    -   Flowers that can last ten days or more as cut flowers;    -   Moderate fragrance;    -   Upright plant that generally grows two to three feet tall;    -   Uniform branching;    -   Dark-green, matte foliage;    -   Its broad prickles;    -   Above average resistance to blackspot;    -   A plant that grows and blooms very well, both, in a greenhouse,        and outdoors as a perennial garden decoration or in large        containers.

The new invention and its parents all have hybrid-tea type, exhibitionform flowers. It is easily distinguished from its parents.

-   -   This new invention, ‘BENsiete’, has flowers of a soft,        apricot-pink. The seed parent in this cross, ‘Perfection’, has        flowers of a solid medium-pink. The flowers of the pollen        parent, ‘JACecond’, are a solid red.    -   This new invention has flowers that expand to 2¾ to 3½ inches        across, on average. The flowers of ‘Perfection’ are expected to        expand 1¾ inches across, on average. Open blooms on ‘JACecond’        average 4 inches across,    -   ‘BENsiete’ is larger than its seed parent, ‘Perfection’, a        miniature rose which has a compact bush that matures at 18 to 24        inches high. ‘BENsiete’ is much slower growing than its pollen        parent, ‘JACecond’, which can grow up to 5 feet tall and 4 feet        wide in its first year. ‘BENsiete’ is not expected to reach more        than 18 inches in its first year and 2½ to 3½ feet when mature.    -   Both ‘JACecond’ and new invention have flowers borne primarily        singly on an upright plant. ‘Perfection’ has flowers borne in        clusters on a compact and bushy miniature bush.

Perhaps the rose from this same breeding program most closely resemblingthis new invention is ‘BENpete’ (not patented) with it shares the samepollen parent, ‘JACecond’. Visually, it is evident that the flowers ofboth BENpete and this new invention have hybid tea-type, exhibitionform, and that both plants have an upright habit. This new invention and‘BENpete’ have the similar open bloom size and petal counts. The mostnotable differences are:

-   -   This new invention has soft, apricot-pink flowers, while        ‘BENpete’ has predominately red flowers with white at the base        and on the reverse of the petals.    -   Both plants have semi-glossy foliage, though the foliage of        ‘BENpete’ is somewhat smaller and a bit darker.    -   ‘BENpete’ is more apt to have multiple flowers per stem.

Asexual reproduction by cuttings of this new variety in MillstoneTownship, N.J., and Arroyo Grande, Calif., show that all distinguishingcharacteristics of this rose continually come true to form.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying illustration shows flowers from plants grown indifferent locations and at different times of the year.

-   -   1. The largest image, image number 1 taken in January of 2009,        shows buds and flowers in different stages of development, and        some foliage from 2 year old plants grown in a plastic covered        greenhouse in Arroyo Grande, Calif.    -   2. Image number 2, in the upper right hand corner of the        enclosed illustration, was also taken in January of 2009. It is        of flowers from a seven year old plant grown in a glass-covered        greenhouse in Millstone Township, N.J. This image shows one        bloom as the petals began to unfurl, and one bloom at half open,        exhibition stage.    -   3. Image number 3 shows a single bloom as grown in a shaded,        plastic covered greenhouse in Arroyo Grande, Calif., in November        of 2005. This image indicates the fewest petals are from this        lower light condition.    -   4. Image number 4 is flowers and buds from five year old plants        grown out doors in the ground in Arroyo Grande, Calif., in        January of 2009. (It is unusual for roses to be in flower        outdoors in Arroyo Grande in January but the weather had been        unseasonably warm the previous three months.)    -   5. Image number 5, across the bottom of the illustration, shows        a stem with some prickles, leaves, and sepals. This is a        candelabra stem from the same plants used for image number 4.        Color is as nearly correct as it is possible to make in a color        illustration of the character.

BOTANICAL DESCRIPTION OF THE PLANT

Unless otherwise noted, the following observations, measurements, valuesand comparisons are from a four-year-old plant of Rosa hybrida,‘BENsiete’, as grown outdoors in Ipswich, Mass. The plant was receivedin Massachusetts in April of 2008, in a 12-inch plastic nurserycontainer in artificial soil mix. In July of 2008, it was transplantedinto a 5-gallon container in a peat moss and compost mix. Observationwas continued through October. Phenotypic expression varies withenvironmental, cultural, and climatic conditions. Color references aremade using The Royal Horticultural Society Colour Chart, except wherecommon terms of color are used.

FLOWERS

BLOOMING HABIT: This new invention is a repeat blooming rose bush.Flowering stems were strong, and very slightly crooked, usually at asingle node but not consistently at the same node. Flowers were bornemostly singly but also in small clusters of two. New shoots developedfrom nodes immediately below the bloom, beginning their growth in thespring and early summer as the top bud began to unfurl, and in latesummer and early fall after the flower faded. The complete cyclerepeated every 5 to 6 weeks.

BUD form was ovoidal with an acute apex and truncated at the base.Diameters were measured from 10/32 to 19/32 inch with lengths from 20/32to 26/32 inch.

BLOOM size averaged from 2¾ to 3½ inches when fully expanded, but weremeasured from 2 9/16 to 4 inches, often not symmetrical, having thecross diameters different by ⅛ to ½ inch. Depths were measured from 1⅛to 2⅛ inches, relative to diameter. When buds began to open they had anurceolate shape. Opening blooms became high centered, developing aconvex upper profile and a shallow-crescent to deeply concave lowerprofile. Blooms opened slowly, taking 6 days or more until the bloomreached exhibition stage at half open, six days to go from exhibitionstage to full open, and about another six days to go from full open tofade. Cut flowers can last ten days or more.

PETALS were moderately thick and seemed to become thicker as they aged.Substance was excellent. Outer petal edges recurved slightly. The outerpetals were imbricated. Progressing towards the center of the flower thepetals became randomly closer together, in some instances one was on topof another, and the upper halves of the petals were curled and twistedaround one another.

-   -   The UPPER SURFACE of the petals was smooth and satiny; the outer        petals became coriaceous as they aged. Primary veins radiated        out from the point of attachment. Their recession progressed        from ever so slight on the young petals to slight on the older        petals.    -   The REVERSE was satiny and glabrous. The veins were clearly        visible, protruding slightly, and usually became a color        different from the surrounding petal surface.    -   The SHAPE of the outer petals was obovate-rotundate. Inner        petals were obovoid. The outer margin was crescent-shaped with a        notch at the apex. The base of the outer petals was        crescent-shaped. The base of the inner petals was broadly        obtuse.    -   PETAL COUNTS varied from 32 to 80 with 4 to 25 petaloids. The        lower petal and petaloid counts were noted on the flowers grown        in the shaded, plastic covered greenhouse, where light intensity        was lowest.    -   Widths of the outermost petals varied from 1 9/16 to 2 1/16 and        lengths varied from 1⅜ to 2 1/16 inches.    -   Petals did not drop cleanly from the receptacle after fading,        remaining withered and attached for several days.

COLOR visible when the sepals first divided was most often Peach, near29D, but was also observed much lighter on one occasion in mid-July, aCadmium Orange, near 23D.

-   -   During the first few days, the upper surface of all petals was        near white, near 159D, surrounded by Peach, near 29D, along the        margins and around the basal area, where it blended into a        Canary Yellow between 9C and 9D in the basal area. The point of        attachment was a bright yellow, between 3B and 6B.    -   The reverse was an Orient Pink, near 36D, along the margins,        which darkened to a Carrot Red, near 29C, progressing down the        petal, and blending into the medium yellow-green, near 154A, of        the basal area, with veins of a Primrose Yellow near 4C. The        point of attachment was also near 4C. The reverse of the inner        petals was a bit different, with a smaller basal area and more        of the surface being near 36D.    -   When half blown, colors remained mostly unchanged. The reverse        had darkened along the margins to a Salmon, near 27B, which        lightened a bit progressing down the petal to near 29D.    -   When full blown, the upper surfaces of the outer petals were        French Rose, near 49D. The basal area had become an Empire        Yellow, near 11D, and the two colors blended in the midsection        of the petal. The point of attachment was a very light yellow        between 11D and 10D. The upper surface of the inner petals was        fading from the 49D and more of it was near 11D.    -   The reverse had become near 36D with a basal area of a light        Mimosa Yellow, near 8D. The veins were slightly raised and near        white, a color near 158D. The reverse of the inner petals was        almost entirely near 36D as the basal area had noticeably        decreased in size.

VARIATION IN PETAL COLORS: The colors of the flowers vary with climaticand edaphic conditions. Some of these variations may be seen in theaccompanying illustration.

-   -   In June in Essex County, Mass., colors were a bit more orange.        During the first few days there was additional color along the        margins of near 23D, a Cadmium Orange. The entire reverse was a        Carrot Red, near 29C. The basal area of the reverse was a        Marigold Orange, near 28C, with areas of near 12D, a very light        Aureolin, on both sides of the main vein and with occasional        streaks at the edge of the basal area. When half blown, the near        23D along the margins on the upper surface had disappeared from        the edges of the margins, leaving them near 29D. The basal area        had become between 4C and 4D, and the point of attachment had        become near 9C. On the reverse, veins appeared dark green, near        141A, with near 154C along the central vein in the basal area.        Other colors were pretty much unchanged.    -   Flowers on plants grown outdoors, in the ground, in Arroyo        Grande, Calif., (see image 4 in the accompanying illustration)        were lighter and more of a rose pink than flowers grown in the        Eastern United States. On the full open blooms, upper surfaces        of the petals were lighter than 36D, an Orient Pink and edged        with near 36C. The reverse of outer petals was French Rose, near        49D, with a light Neyron Rose, near 55D along the margins. The        reverse of intermediate petals was between 49D and 54D, and        edged with near 55C. The reverse of the inner petals was darker        still, near 55D, with some areas near 49D and near 49C, and all        blending together. Basal areas on the upper surfaces were near        11C. Basal areas on the reverse were near 11D, which also went        up through the center of the petal, and blended outward into the        petal.    -   Flowers grown in Millstone Township, N.J. are overall darker,        with the deepest color, and more of a yellow-orange tone to        them. Flowers grown in the glass-covered greenhouse of the        inventor are shown in image 2 of the illustration.    -   Observations of the flowers from the plants grown in Ipswich,        Mass., and Arroyo Grande, Calif., indicated the colors of the        flowers became lighter and pinker as the intensity of sunlight        increased. Petal counts also seemed to increase as a result of        stronger sunlight.

PETALOIDS were interspersed between the petals, and towards the centerof the bloom; a few seemed intertwined with the stamens. Their color andtexture was the same as those petals immediately behind them. The baseof some petaloids was often narrower, and sometimes only one-half of abase. Some appeared to be attached by a filament. Many were verymisshapen, from half a petal, to distorted, to miniscule. Some wereepipetalous, with stamens or part of a stamen attached to some part ofthe main vein, which was randomly located in the petal. Margins wereobserved as deeply cleft to lobed, double-lobed, or even triple-lobed;sinuate; erose; or any combination of these. The largest petaloidobserved on a full open bloom was 1¾ inches long and wide, having onlythe base abruptly narrowed. The smallest were less than 1/16 inch by ⅛inch, and usually mixed in with the stamens.

SEPALS

There were five sepals permanently attached along the outer edge of thereceptacle. They extended beyond the tip of the bud by ½ inch beforethey began to divide.

-   -   SHAPE was ovate with acuminate apices and truncated at the base.    -   APPEARANCE of the outer surface was semi-glossy when young, and        became matte when mature. The inside surface had a fine        pubescence.    -   COLOR of the outer surface was a medium yellow-green near 144A        and much lighter, near 145A, in the basal area. The inside        surface was a muted light green, between 138D and 191B, with a        basal area and up through the center being a darker        yellow-green, near 146A.    -   MARGINS were ciliated. The margins of the two outermost sepals        also had glands, stipitate glands and fine foliation.    -   CHARACTERISTICS of the two outer sepals: There were usually two        foliar appendages along each margin, with one being shorter than        the other. Usually, they were sinuate or lunate, and the largest        of these was bowed. Along the margins of these foliar appendages        were smaller acicular appendages, glands and stipitate glands,        some with long stipes. The size of all appendages decreased        toward the base of the sepal.    -   The apices of these two outer sepals were foliated with one or        two subulate appendages along one margin and three or four along        the opposite margin. The size of these appendages decreased        toward the tip.    -   CHARACTERISTICS of the one sepal in-between the inner and outer        sepals was often a combination of both the inner and outer        sepals, dividing down the center, though there were many        occasions when both margins were foliated.    -   SIZE: The width of all sepals varied from 12/23 to 15/32 inch.        Lengths of the outer two sepals were measured at 1 6/32 and 1        7/32 inches. The two inner sepals were measured at 1 4/32 and 1        5/32 inches long. Lengths on the one sepal in-between varied        from 1 to 1¼ inches.

RECEPTACLE

RECEPTACLES were conical, truncated at both the top and base. Thesurface was semi-glossy but became matte as it aged. It appearedglabrous. The diameter at its widest part was 25/64 to 14/32 inch. Theheight was most often about 11/32 inch but was measured up to 15/32inch. The color was a light Scheele's Green, near 144B. It was oftenflushed with a Greyed Red near 178A on the sunward side. An aerial viewshowed the top surface to be ovoid, about 20/32 inch long and 19/32 inchtapering to 17/32 inch wide. A thick covering of tight stands of long,soft hairs was between the stamens and pistils.

REPRODUCTIVE ORGANS

STAMENS, FILAMENTS AND ANTHERS:

-   -   They appeared to be attached throughout upper surface of the        receptacle, from the outer edge to the alveola at the center of        the receptacle.    -   Approximately 140 to 154 (or more) were arranged regularly        around the outer edge of the receptacle. There were additional        shorter ones protruding from amongst the tomentum that covered        the top surface of the receptacle; at one count there were 27 of        these.    -   Some of the inner ones and some of the outer ones were folded        over, even after the flower had faded, giving the appearance of        having very short filaments.    -   FILAMENTS were a light Chartreuse Green, near 1D. Their lengths        ranged from 3/16 to 6/16 inch.    -   ANTHERS were a very light Primrose Yellow, near 4D.    -   Pollen sacs were Maize Yellow, near 21B.

PISTILS, STYLES AND STIGMAS originate in the alveola at the center ofthe upper receptacle surface.

-   -   Quantity ranged from 140 to 200.    -   STYLES were very thin. Those in and toward the very center were        straight. Those that were closest to the stamens were curved        somewhat, apparently from lack of support. Lengths varied from        3/16 to ½ inch, with the shorter ones toward and in the center.        Within any one flower, lengths usually were not more than 3/16        inch different. Their color was a dark red, between 46A and 53A        toward the top and the rest was a white, near 155A.    -   STIGMAS were a dull Amber Yellow between 18C and 161C.

HIPS were not observed. This new invention does readily self pollinate.

PLANT

PLANT HABIT was upright and uniformly branched. The general height ofthese plants is 24 to 36 inches, with a width of 30 inches. Undercertain growing conditions, the plant may grow a foot taller. (SeeVARIATIONS REGARDING THE PLANT following the section on PRICKLES.)

-   -   MAIN CANES had a diameter of 15/32 to ½ inch. The color of these        older canes was a medium green between 147B and 195A.    -   FLOWERING STEMS had a diameter of 3/16 inch at the base tapering        to 2/16 at connection to the peduncle. Their length was quite        variable, from 6½ to 13⅜ inches. They tend to be slightly        crooked at a node but not consistently at the same node. In the        summer it was noted that most flowering stems had 4 to 6 nodes.        In the spring there were usually 7 to 9 nodes. At the top of        each flowering stem, at the juncture with the peduncle were at        least one small stipulate appendage paired with the same or a        one to three-leaflet leaf. New growth was near 144B and became        between 147B and 137C.    -   PEDUNCLES were straight and very strong with a semi-glossy        surface. Lengths were most often measured about 1 5/16 inches        but varied from 1 6/32 to 1 17/32 inches. Diameters were        generally 6/32 inch right below the receptacle, tapering to 4/32        inch and then increasing to 5/32 inch at the base. The color was        near 144D below the receptacle and became near 144A at the base.        They were flushed on the sunward side with near 178B. The        surfaces had numerous stipitate glands, decreasing in quantity        toward the receptacle. The glands were near 178B.

FOLIAGE

LEAVES were arranged alternately on the stems. They were pinnatelycompound with five to seven leaflets but also with three. Seven-leafletleaves were about one inch longer than five-leaflet leaves.

-   -   Five-leaflet leaves were measured 3⅛ to 4½ inches long.    -   Seven-leaflet leaves were measured 4 to 5 1/16 inches long.

LEAFLETS were ovate. Serration was simple with a gland at the tip ofeach serrate. The length of terminal leaflets on mature leaves variedfrom 2 15/32 to 2 23/32 inches. Widths varied from 1 9/16 to 1 13/16inches.

-   -   The upper surface was glabrous and matte to semi-glossy. The        main and primary lateral veins are equally recessed.    -   The undersurface was matte and coreacious. The venation pattern        was costate, with the main vein protruding entirely and the        primary lateral veins protruding somewhat.    -   Color on the upper surface of young leaflets was a medium green        between 137C and 147B, with the glands along the margins of near        185A. The reverse was a medium green between 143B and 191A,        flushed with varying degrees of near 185A.    -   Color of older foliage was a dark green between 149A and 139A.        The reverse was between 137B and 147B. Main veins were lighter,        near 144C.

PETIOLE, RACHIS AND PETIOLULES: The coloring and texture of the petiole,rachis and petiolules were the same.

-   -   Color on young leaves on the entire adaxial surface was heavily        flushed a deep purple-red, between 183A and 178A. The reverse is        a medium green between 195A and 146B.    -   Color on the old foliage on the adaxial surface was a medium        Scheele's Green, near 143B, in the groove, with the ridges the        same dark green color as the upper leaflet surface. The reverse        was a lighter Scheele's Green, near 144B.    -   On the adaxial surfaces, there were stipitate glands along all        ridges; grooves were glabrous with the exception of many stiff        hairs at the juncture of the leaflets.    -   The abaxial surfaces were glabrous with the exception of a        single prickle, or two or three prickles along the rachis.    -   Length of the petioles on the seven-leaflet leaves varied from ⅝        to ⅞ inch. On the five-leaflet leaves it was longer, varying        from 23/32 to 1 5/32 inches.    -   Lengths of the rachis on the seven-leaflet leaves varied from 1        4/16 to 1 15/16 inches. Rachises on the five-leaflet leaves were        shorter, varying from 10/16 to 11/16 inch.    -   The length of the petiolules to terminal leaflets was not        affected by the number of leaflets or the overall length of the        leaf. They ranged in length from 19/32 to 25/32 inch.

STIPULES were located in even pairs attached to the base of the petiolefor about 13/32 inch with an additional 5/32 to 10/32 angled outward atabout a 45° angle from the petiole. Margins were somewhat curled under,to the greatest degree at the base, and decreasing to becoming flat ator before the point where the tip begins to angle outward. The marginsare lined with gland-tipped serrates with a few stipitate glands on andbetween some serrates. The color was near 137B.

PRICKLES

PRICKLES can be numerous or ‘average’ in number. When young, theytapered to a point, angled downward, and curved or hooked downward. Onthe older canes, they had developed into a broadly deltoid profile, butstill slightly angled downward. The shape of the bases was verynarrow-oblong. Widths of the bases varied from 3/32 to 4/32 inch,relative to the overall size of the prickle. The bases of medium sizedprickles were generally the same as the length as the prickle; the basesof the shorter prickles were shorter than the prickle; and the bases ofthe longest prickles were usually longer than the prickle.

-   -   On main canes, there was one in the first one inch from the base        of the cane and five in the first two inches. They were        generally 4/32 to 11/32 inch long.    -   On the primary laterals, there were seven to eight in three        inches. Lengths varied from only 1/16 inch long to ⅜ inch long.    -   On flowering stems there were four to five in three inches and        nine to eighteen in five inches. Lengths varied from 2/16 to        5/16 inch.        When young, the base of the prickle was near 182A, a medium        shade from the Greyed-Red Group, and a darker Greyed-Purple,        near 183A toward and at the tip. Those prickles exposed to more        sun were entirely near 183A, but only on the side receiving the        most sun. As they aged, the color lightened to near 165C from        the Greyed-Orange Group. When old, the prickles had become a        lighter beige-color, between 165D and 199D.

VARIATIONS REGARDING THE PLANT: A difference in day and nighttemperatures greater than around 30° F. can cause the plant to send uplong, very fast growing canes. These may originate from below theground, at or near the base of the plant. They are often referred to ascandelabras because of the large number of blooms originating near thetop of a usually long cane. On this new invention, they terminated in alarge spray of flowers. The color of these canes was the same as newgrowth, and gradually became the same color as the older wood on theplant. The quantity of prickles was much greater on these canes, withmore than 20 in each of the first two inches from the base. The largestleaves were found on these candelabras.

RESISTANCE to blackspot was better than average. The plant has onlyaverage resistance to powdery mildew. Downy mildew and rust were notobserved.

HARDINESS was tested in zones 5 through 10. While the plant was notkilled by the cold nor bothered by the heat, it did not survive a springof freezing and thawing.
